STEERING-WHEEL CARRIAGE.

SPECIFICATION forming part of Letters Patent No. 421,884, dated February18, 1890.

Application filed November 15, 1889- Serial No. 830,457- (No model.)

To all whom it may aoncerm Be it known that I, DANIEL BEST, a citizen ofthe United States, residing at San Leandro, Alameda county, StateofCalifornia, have invented an Improvement in Steering-Wheel Carriages;and I hereby declare the following to be a full, clear, and exactdescription of the same.

My invention relates to the class of steering apparatus speciallyapplicable for roadlocomotives, traction-engines, and similar, heavyvehicles.

My. invention consists in the novel con struction and arrangement of thesteeringwheel carriage hereinafter fully described, and specificallypointed outin the claims.-

The object of my invention is to provide a simple and effectivesteering-wheel carriage, which can be operated easily and with the leastamount of friction, at the same time being steady in its action anddurable.

Referring to the accompanying drawings for a more complete explanationof myinvention, Figure 1 is a plan view of my steeringwheel carriage.Fig. 2 is a side elevation. Fig. 3 is a detail of the bearing at theaxle end.

Ais a portion of the main frame of the vehicle. To the under side ofthis is firmly bolted or otherwise secured the circular guide-track B.

O is a swinging frame, which carries the boxes in which the axle D isjournaled, said axle carrying at its center the steering wheel E, whichlies and plays between the sides of the swinging frame 0. This frame 0bears up under the circular track B through the intervention ofanti-friction rollers F, which are mounted upon the side bars of theframe have grooved faces fitting the under side of the circular track13. The sleeves H have also an outer flange h, with an inturned upperend M, which bears over a flange b on the outer surface of the circulartrack 13, and serves to further steady and hold the parts together.Mounted upon the top of the inner flanges h of the sleeves are the sidesteadyingrollers J, which bear against the inner surface of the circulartrack B.

Mounted upon the rear ends of the side bars of the frame 0 are therelief-rollers K, which bear against the inner surface of the circulartrack 13. From this construction it will be seen that the frame 0, withits axle D and steering-wheel E, has a swinging motion through a circleor portion thereof, being guided in this motion, first, by means of themain carrying-rollers F and steadied laterally bythe rollers I-at eachend of the axle, and further steadied by the inner bearingrollers J andthe flange top 77?, so that the movement of these parts is a perfectlytrue one, not subject to variation or deflection of any kind, and havinga minimum of friction. The sleeves on the outer ends of the axle do notinterferewith the proper rotation of said axle, but at the same timefurnish suitable bearings for the rollers I and J and for the flange top72, holding the parts well together. The relief-rollers K are to ease upany sudden jar which the steering-wheel may receive by reason ofencountering an obstruction, and they do this by coming in a kindofrolling contact With the circular track B.

The swinging movement of the axle may be accomplished in anysuitablemanner, and I have here shown for this purpose the out- Wardly extendingarms a of the swinging frame 0, to which are attached the chains L, therear ends of which Wind up on and unwind from a crossshaft M, operatedby suitthe anti-friction rollers I, mounted on the sleeves and bearingunder the fixed circular track, substantially as herein described.

2. In a steering-wheel carriage, the combination of the fixed circulartrack, the swinging frame, the axle carried by the frame, the

' steering-wheel on the axle, the anti-friction rollers F on each end ofthe swinging frame bearing under the circular track, the sleeves II oneach end of the axle, and the anti-friction rollers I, mounted on thesleeves and bearing under the circular track, substantially as hereindescribed.

3. In a steering-wheel carriage, the combination of the fixed circulartrack, the underlying swinging frame, the axle carried thereby, thesteering-wheel on the axle, the outwardly-projecting braces G from eachside of the swinging frame, the independent sleeves II, secured to theouter end of the braces and mounted upon the ends of the axle, and theanti-friction rollers I, carried by said sleeves and bearing under thecircular track, substantially as herein described.

4. In a steering-wheel carriage, the combination of the fixed circulartrack, the underlying swinging axle, the independent sleeves mounted onthe axle ends and having vertical inner flanges 71-, the horizontalrollers J on the top of said flanges, bearing against the inner surfaceof the fixed track, and the antifriction rollers I, mounted 011 thesleeves and bearing under the fixed track, substantially as hereindescribed.

5. In a steering-wheel carriage, the combination of the fixed circulartrack having the outer flange l), the swinging axle under said track,the independent sleeves mounted 011 the axle ends, said sleeves havingvertical outer flanges with inturned upper ends 72?, hearing over theflange of the fixed track, and the anti-friction rollers I on thesleeves, bearing under the fixed track, substantially as hereindescribed.

6. In a steering-wheel carriage, the combt nation of the fixed circulartrack having the outer flange h, the swinging axle, the independentsleeves mounted on the axle ends and having inner and outer verticalflanges, the latter of which has an inturned end bearing over the outerflange of the fixed track,

the rollers J on the upper ends of the inner flanges, and the rollers I,mounted on said sleeves and bearing under the fixed track, substantiallyas herein described.

7. In a steering-wheel carriage, the combination of the fixed circulartrack B, having an outer flange Z), the swinging frame 0, the axle D,carried by the frame, the wheel E on the axle, the braces G, extendingoutwardly from the swinging frame, the independent sleeves H, secured tothe braces and mounted 011 the axle ends, said sleeves having thevertical flanges h and h, the latter of which has an inturned endbearing over the flange of the fixed track, the rollers J 011 the topsof the flanges hand bearing against the inner surface of the fixedtrack, and the anti-frietion. rollers I on the sleeves, bearing underthe fixed track, substantially as herein described.

8. In a steeringwheel carriage, the combination of the fixed circulartrack B, the swinging frame 0, the axle I), carried by the frame, thesteering wheel on the axle, and the relief-rollers K, mounted on therear ends of the swinging frame and bearing against the inner surface ofthe fixed track, substantially as herein described.

9. A steering-wheel carriage comprising the following parts, incombination, to wit: the fixed circular track 13,having an outer flange1), the swinging frame C, the axle I), mounted in the frame, thesteering-wheel on the axle, the on twardly-extending braces G, carriedby the swinging frame, the anti-frietion rollers F on the ends oftheswinging frame and bearing under the fixed track, the independentsleeves II, secured to the braces G and mounted on the axle ends, theholding-flange la of said sleeves, bearing over the tracktlange, andinner bearing-rollers .l' of said sleeves, acting against the innersurface of the track, and the anti-friction rollers I, mounted on thesleeves and bearing under the fixed track, all arranged and adapted tooperate substantially as herein described.

In Witness whereof I have hereunto set my hand.

DANIEL BEST.
